Given numbers are 721, 399, 264, 378

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 399 are 3 x 7 x 19

Prime factors of 264 are 2 x 2 x 2 x 3 x 11

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 721, 399, 264, 378

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(721, 399) = 41097

GCD(721, 399) = ( 721 x 399 ) / 41097

= 721 / 399

= 721

Step2:

LCM(7, 264) = 1848

GCD(7, 264) = ( 7 x 264 ) / 1848

= 7 / 264

= 7

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 721, 399, 264, 378 is 1
